AbstractDoes Iran, which is known in political science literature as a developing, oriental and ancient country, have specific, examinable and predictable models in a way that can be applied to foreign policy studies? In this study the author intends to analyze six models of Iranian foreign policy between the two revolutions (from the constitutional to the Islamic); these patterns have been fluctuating dialectically between an idealism embedded in the Iranian grieving ontology and realism as it relates to the international environment. At the beginning, the nostalgic worldview of Iranians that is a reflection of their subjective collective constructs is analyzed. Then counter-scientism and anti-positivism in Iranian epistemology is studies. The outcome of these two is the absence of realism as the most significant paradigm of foreign policy. In order to prove the assumption, six models of Iranian foreign policy will be briefly assessed with the aim of demonstrating how the unconsciousness of Iranian ancient civilization and mystical and severely anti-science and anti-reality covers have given life to an anti-reality which has caused Iranian foreign policy patterns to be infused with unwarranted idealism. The dialectic between the two different atmospheres, however, has given way to creative models; and the Iranian Ministry of Foreign Affairs has been efficient and taken the initiative in their design, implementation and assessment.
